Andrea Nusser Lighting & Interior Design sent us images of a project they recently completed for Frankfurter Welle.

Frankfurter Welle is a commercial property in the centre of Frankfurt am Main/Germany. The project is a collaborative effort by offices of Mrs. Nusser and Mr. Henn.

In early 2008, the office Andrea Nusser lighting & interior design illuminated together with the office Henn for the Luminale in Frankfurt am Main the entire area of the Welle. This property is located directly behind the Alte Oper and covers a complete square. Even then, the operating company complained that the galleries were very poorly lit and maintenance was a real imposition. The visibility of these buildings to the averages of Reuterweg waterway in the Welle was also not guaranteed.

Mrs. Nusser and Mr. Henn began in 2008 with the illumination of the glass facades towards Reuterweg using RGB-LED-lines. Then the two lighting designers took care of the interior design of the galleries.

The concept, developed by them, intended a significant reduction of the number of luminaries, from 1440 individual lights on the 18m-high ceiling to 15 lights in the malls, with an appropriate wattage. The mounting height should be moved much further down, since a lamp replacement was associated at this time of enormous human cost and technical complexity.

The new approach not only meets the demands of an energy management and maintenance improvements, it also has significant advantages in optical elements such as size, color and adaptation to the environment. The ceiling, which had been broken like a “Swiss cheese” shines, now as white and homogeneous solid surface.

Electricity costs, which amounted previously to 57.000 € per year for both galleries, reduce by about 95% to around € 3.195 € per year, the cost of maintenance is also reduced to a fraction of the cost and in the meantime in 2008 mounted glass facade illumination with RGB LEDs comes more clearly to effect.

To realization came the products from iGuzzini – the Maxiwoody. These give according to the previous calculations, each with 400W and only 10 firing points per gallery – from the 5 Plateas the elevator housing (central area reduction) apart – the necessary lux on the floor (on average 100 lx). The mounting height of the lamps, as well as the mirror with textured surface that was collecting the light directed upwards to about 2 / 3 and reflect back down, were determined after a big mock-up before. Another improving of the lighting plan is to sink the lighting level after midnight. The lighting is switched off to 2 / 3, so that, on average, scored at least 8 lx on the floor. This reduces again the power costs down significantly.

The grazing by the mirror glare illuminates the closed gallery ceiling, which in addition to the improved visibility of building averages for the passer even contributes supportive to highlight the LED lighting on the facade. To test the lighting situation was also seen from the bridges here, so that is, using internal glare screens, the glare of the staff of the gallery located in the offices right and left to be ensured.

They chose of this light, since the formal language of rotationally symmetric Maxiwoody is most appealing. The ballast is hidden behind the elegant lamps actual body and fits with the silver body color inconspicuously on the gray columns.
